The minimum pipe stiffness shall be 46 PSI. All seams on the completed pipe shall be thermally fused. Glued seams will not be allowed. The pipe shall be produced with integral bell and spigot end construction with elastomeric seals and shall conform to all requirements of ASTM D-3212. Joining shall be by rubber gaskets that conform in all respects to the physical requirements specified by ASTM F-477 for low head applications.

6 The lubricant used for assembly shall be as recommended by the manufacturer and shall have no detrimental effect on either the pipe or the rubber gasket. The average nominal inside diameter and manufacturing tolerance shall be as listed for stiffness Series 46 in Table IA for open profile pipe and Table IB for closed profile pipe of ASTM F-794. The pipe shall be furnished in nominal lengths of 13 feet and shall contain all markings required by ASTM F-794. One sample of each size pipe specified, from the production runs for this project, shall be tested in accordance with the requirements of ASTM F-794.

7 The manufacturer shall furnish certification that the pipe was manufactured, sampled, tested and inspected in accordance with and has been found to meet the requirements of ASTM F-794 in all respects. Fittings shall be in accordance with ASTM F-794, D-3212, and/or D-3034 as applicable, with stiffness and wall thickness equal to or greater than the pipe . Adapters shall be provided to join different materials. (c) PVC Corrugated SEWER pipe : Unless amended on the construction drawings or elsewhere in these SPECIFICATIONS , SEWER pipe 8-inches through 18-inches may be Polyvinyl Chloride Corrugated SEWER pipe with a smooth interior, manufactured in accordance with ASTM F-949.

8 The pipe shall be produced with integral bell and spigot construction with elastomeric seals and shall conform to all requirements to ASTM D-3212. Joining shall be by rubber gaskets that conform to the requirements of ASTM F-477. The pipe shall be furnished in nominal lengths of feet and shall contain all markings required by ASTM F-949. One sample of each pipe size specified, from the production runs of this project, shall be tested in accordance with the requirements of ASTM F-949. The manufacturer shall furnish certification that the pipe was manufactured, sampled, tested, and inspected in accordance with and has been found to meet the requirements of ASTM F-949 in all respects.

9 Fittings shall be in accordance with ASTM F-949, D-3034, and/or D-3212 as applicable, with stiffness and wall thickness equal to or greater than the pipe . Adapters shall be provided to join different materials. _____ July 27, 1995 SEWER SPECIFICATIONS / DETAILS (MS) XV-2 3. Reinforced Concrete pipe : Unless amended on the construction drawings or elsewhere in these SPECIFICATIONS , all sanitary SEWER pipe 18-inch in diameter and larger may be reinforced concrete pipe , Class IV minimum, manufactured with "C" thickness, and conforming to STANDARD Specification for Reinforced Concrete, Storm Drain, and SEWER pipe , ASTM C-76 and with the following modifications: Sacrificial Concrete: This specification is intended to provide sacrificial concrete on the inside of all reinforced concrete SEWER pipe .

10 Amendments will be made, as necessary, in the Special Provision Section of this contract to maintain this design and/or specify other acceptable measures when sacrificial concrete is not feasible for large diameter pipe . In lieu of sacrificial concrete, reinforced concrete pipe may be manufactured with calcareous aggregate. If this option is chosen, all coarse aggregate used in the pipe shall be limestone or dolomite, and the alkalinity of the finished pipe shall be a minimum of 50% when expressed as calcium carbonate equivalent.
